PREFACE 

American zoological writers who have published books or scientific papers during the 
past decade show little uniformity in their reference to larger groups of animals. Of 
course no zoologist wishes to be limited in the choice of names which seem to be most 
appropriate; no one wishes to have imposed on him terms which he is ordered to use; and 
none desires to have nomeclature become fixed and inflexible. Of all the rewards that 
Science gives to her retainers those most prized and enjoyed are independence and the 
right to change old dogmas as soon as the discovery of new truths makes them illogical. 
Yet because the species of animals now number several hundreds of thousands, the 
sorting of species into groups must necessarily be continually more accurate and critical. 
Furthermore, there are men who through ignorance, inertia, or bigotry take little or no 
cognizance of the progress of current scientific evidence and opinion. For example, cer- 
tain writers of recent textbooks use such old terms as Annulata and Anura when the 
most thoughtful and competent students of annelids and amphibians agree that Annelida 
and Salientia are to be preferred. Dr. R. E. Snodgrass, who has recently studied the 
anatomy of onychophorans in detail, is convinced that these animals cannot be called 
arthropods because their muscular systems have quite different relations to nervous 
structures from those which obtain in arthropods. Dr. J. P. Moore does not believe that 
onychophorans may be included among amielids. There seems to be no alternative but 
to set off Onychophora as a group by itself. 

Those who know animals and their classifications in detail perhaps may enjoy using 
various names for the same group and delight in thus displaying their technical knowledge, 
but a novice who refers to two or three textbooks and finds the same group called by 
two or three names is greatly confused. In an attempt to bring about greater uniformity 
and more careful selection in the use of zoological group names the writer was authorized 
to form an intormal committee and to prepare a list of phyla, classes, and orders of 
animals which would represent current good usage. This action was taken by Section F 
of the American Association for the Advancement of Science at the Boston Meeting ; 
December, 1933. 

Since then many persons who appeared to be interested have been consulted. The 
following gave advice in connection with the groups mentioned : 

Invertebrata : A. H. Clark, B. G. Chitwood, Roy Miner, L. E. Noland, H. S. Pratt, 
Waldo Schmitt, H. J. Van Cleave. 

Protozoa : L. E. Noland, and forty-odd protozoologists to whom he sent a question- 
naire.

Coelenterata : Elizabeth Dekhmann (except Zoantharia). 

Aschelminthes : B. G. Chitwood, M. C. Hall.

Schmitt, J. P. Visscher, C. B. Wilson.

Pycnogonidia : L. J. Cole; Arachiiida : //. £. Eiving. 

Insecta : C. L. Kennedy, Z. P. Mctcalj. J. G. Needham, H. G. Barber, H. E. Ewing. 

Mollusca : P. Bartsch, H. Rehder. 

Chordata : C. W. Gilmorc, \V. K. Gregory.

Those whose names appear in italics furnished essentially the terms that appear in the 
following pages. While the writer gladly acknowledges the obligation to those persons 
and appreciates greatly the work they did, they are not to be held responsible for the 
published list. The differences of opinion among zoologists in the United States were 
found to be so great that there was little hope of agreement and the editor finally did 
what seemed to him best. 

Perhaps forty per cent of those consulted strongly urged the use of uniform endings 
for the larger groups of animals. The difficulty encountered in this connection was that 
protozoologists, helminthologists. conchologists, ornitholgists, etc. had already moved 
more or less in the direction of uniformity and each group of specialists had a tendency 
to adopt a different system. After long consideration the editor has used the system in 
vogue among protozoologists and students of some other groups, as it seemed to be at 
present more generally in use than any other. The endings are as follows : Phylum and 
Subphylum, — a; Class, — ea; Subclass, — ia ; Order, — ida ; Suborder, — ina. In presenting 
this report to Section F it is not supposed that uniform endings shall be adopted as official, 
or even recommended. The zoological world had perhaps best be left to make its own 
choice. In the list the names in the first column represent what the editor after con- 
sultation believes to be best current usage; those in the second column are what a few 
zoologists would like to see used, but perhaps in presenting these the editor is "a hundred 
years ahead of his time." In any attempt to attain uniformity difficulties arise. For 
example, Dr. Steiner points out that two names suggested as suborders under Nematoda 
are objectionable because identical names already have good standing as genera in the 
same group (Rhabditina Cobb 1922, Chromadorina Filipjev 1926). 

Another matter about which there is wide disagreement is whether there should be 
few or many groups — the old controversy between "lumpers" and "splitters." Shall there 
be ten or thirty phyla, or orders of insects ? The position has been taken that it is more 
truthful, and therefore more scientific, to present many groups ; otherwise it is necessary 
to compromise to the extent of grouping things together which have remote or insig- 
nificant relationships. To the objection that students cannot be expected to master such 
a long list of technical jargon there is only one answer. It is better to tell students part 
of the truth frankly than to falsely affirm that they are learning a complete and simple 
story. Biology is not always simple and clear. It therefore seems proper to say to a 
student in an elementary course, "of the thirty-odd phyla of animals, or orders of insects, 
only ten or a dozen which are of particular biological significance to you will be studied," 
rather than, "for convenience and simplicity all animals, or all insects, are presented 
under ten phyla, or orders, which may be easily remembered." Science is truth. 
Classification must be expected to grow more complex as knowledge increases and 
becomes more critical. 

In most groups the authors' names and the dates following correctly indicate when a 
particular scientific name was given to a group, but these should be used with caution 
for in cases where no specialist could be found to furnish accurate information (birds, 
fishes, etc.), the editor browsed through systematic works and found such information, 

[3] 



some of which later proved to be incorrect. For example, some references credited to 

Lamarck by various writers are for vernacular names which should have no scientific 

standing as scientific names. The following groups have been carefully corrected by 

specialists and are believed to be reliable for authors and dates : Protozoa, Porifera, 

Coelenterata (except Zoantharia), Platyhelminthes, Nemertea, Acanthocephala, Nematoda, 

Bryozoa, Brachiopoda, Echinodermata, Annelida, Arachnida, Crustacea, Insecta, Tuni- 

cata, Amphibia, Reptilia, and Mammalia ; other groups may not be.

SECOND EDITION 

As there is continual demand for this list, which has been out of print for several 
years, it seems desirable to publish a second edition. A few changes have been made 
and the following persons made suggestions for the revision. A. H. Clark suggested 
the term Hemizoa and other general changes. Grateful acknowledgment is made to 
G. W. Wharton who corrected the proofs for the list. An excellent discussion of various 
modern systems of classification will be found in Libbie H. Hyman's "The Invertebrates : 
Protozoa through Ctenophora," 1940:22-43. 

Invertebrata : A. H. Clark, C. G. Bookhout; Protozoa: R. R. Kudo; Porifera: M. W. 

de Laubenfels ; Nemertea : W. R. Coe ; Acanthocephala : H. J. Van Cleave ; 

Bryozoa: R. C. Osburn; Annelida: Grace E. Pickford; Arthropoda : R. E. Snod- 

grass ; Pycnogonida : Joel W. Hedgpeth ; Arachnida: Elizabeth B. Bryant; 

Acarina: G. W. Wharton; Myriapoda: Nelle B. Causey; Crustacea: Fenner A. 

Chace; Insecta: C. F. W. Muesebeck and colleagues; Tunicata: W. G. Van Name; 

Vertebrata : E. C. Horn, I. E. Gray.

THIRD EDITION 

The second edition of this list was so full of errors that it was never sent to the 
general biological public. In the revision for this third edition the list of groups that 
has "uniform" endings has been omitted. The following persons have furnished informa- 
tion for the groups indicated : Invertebrata, Libbie H. Hyman and M. W. de Laubenfels ; 
Protozoa, R. R. Kudo; Porifera, M. W. de Laubenfels; Platyhelminthes, Libbie H. 
Hyman and H. W. Manter ; Cestoda, Robt. P. Dollfus; Nemertea, Libbie H. Hyman 
and Arthur G. Humes ; Brachiopoda, Preston E. Cloud, Jr. ; Annelida, Olga Hartman and 
Grace E. Pickford ; Crustacea, Fenner A. Chace, Jr. ; Arachnida, Alexander Petrun- 
kevitch ; Acari, G. W. Wharton ; Pycnogonida, Joel W. Hedgpeth ; Myriapoda, Nelle B. 
Causey; Insecta, F. M. Carpenter and Charles L. Remington; Mollusca, H. A. Rehder; 
Tunicata, W. G. Van Name and A. G. Huntsman; Fishes, Carl H. Hubbs; Amphibia 
and Reptilia, Grace L. Orton; Aves, Ernst Mayr and Alexander Wetmore. For trema- 
todes Dawes (1946) "the Trematoda" has been followed, for fishes, amphibians, and rep- 
tiles the classification in Romer's (1945) "Vertebrate Paleontology" has been used, and 
for mammals that in Simpson's (1945) "The Principles of Classification and a Classifica- 
tions of Mammals" has been followed.
